Application of Polyethylene Cling Film to Underpin Moist Burn Wound Therapy

Background Dermal burns (partial thickness burns) are the most painful trauma with two types of pain background pain with additional procedural pain, one of the best tolerable mode of treatment that commonly used now adays is treatment with MEBT ointments to maintain the moist and warm wound environment suitable for regeneration of epidermal cells, and to reduces pain. Moist wound dressings retain moisture, heat, body fluids, and biofilm with medication. The assumption is that the polyethylene film will maintain the ointment and its effect more than to be used merely. Patients and methods Prospective study to evaluate treatment of patients with partial thickness burns conservatively with MEBT ointment as a control group and MEBT ointment + Cling Film, 63 patients being admitted to the burn center at Azadi teaching hospital during a period of one year starting from June 2018 till June 2019. The inclusion criteria including all patients between 10-95% partial thickness burns of various age, sex and skin types. Results Very much decrease in procedural and background pain, better joint movement in physiotherapy decrease in crust formation, increase maceration of eschar, better cost- effectiveness, less days of hospital stay. Aim; in Iraq circumstances we have to use the most cost effective measures to reach our goals in managing the burn wounds the moist trend which is now being proved it gives better healing with less pain, with best criteria of wound dressing . Conclusion Easily applicable, less painful, non-coasty over all, better condition of patient during course of management, reduced length of hospital stay and lower treatment costs, appropriate wound healing with living tissue , less joint stiffness problems

Recent Advances in Packaging and Edible Coating for Shelf Life Enhancement in Fruit Crops

In today’s competitive world, packaging and edible coating play a significant part in producing usefulness user affable products for marketing. Due to several drawbacks of conventional packaging materials (wooden boxes, gunny bags, pallet, pallet bins, Wire-Bound Crates etc.) new technologies of polymeric films (LDPE, HDPE, Shrink film, Cling film) are adopted. By use of polymeric film (non perforated) modified atmosphere is obtain within the package, which subsequently helps to enhance shelf life of fruits. Application of thin layers of edible coating onto fruit surface helps to modify inner environment of fruit which causes similar effect to the modified atmospheric storage. This technological strategies are helpful to retard water loss, reduces skin damage caused by friction, changes in gaseous composition, moisture content, volatile aromas, and transport of solutes from the fruits overly enhance cosmetic appearance, decreasing ripening process and rise shelf life of fruits.

Pre-screening the intrinsic angiogenic capacity of biomaterials in an optimised ex ovo chorioallantoic membrane model

Biomaterial development for clinical applications is currently on the rise. This necessitates adequate in vitro testing, where the structure and composition of biomaterials must be specifically tailored to withstand in situ repair and regeneration responses for a successful clinical outcome. The chorioallantoic membrane of chicken embryos has been previously used to study angiogenesis, a prerequisite for most tissue repair and regeneration. In this study, we report an optimised ex ovo method using a glass-cling film set-up that yields increased embryo survival rates and has an improved protocol for harvesting biomaterials. Furthermore, we used this method to examine the intrinsic angiogenic capacity of a variety of biomaterials categorised as natural, synthetic, natural/synthetic and natural/natural composites with varying porosities. We detected significant differences in biomaterials’ angiogenesis with natural polymers and polymers with a high overall porosity showing a greater vascularisation compared to synthetic polymers. Therefore, our proposed ex ovo chorioallantoic membrane method can be effectively used to pre-screen biomaterials intended for clinical application.

Effects of Cling Film Draping Material on Body Temperature of Mice During Surgery

General anesthesia induces many systemic effects, including thermoregulatory impairment and subsequent perioperative hypothermia. Due to the animals’ small size, monitoring and maintaining body temperatures in laboratory rodents during anesthesia is important for successful surgical outcomes and prompt anesthetic recovery. Draping materials have the potential to aid in thermal support during surgical anesthesia. In this study, rectal and surface (infrared) temperatures were measured in C57BL/6 mice under isoflurane anesthesia every 5 min for the duration of a 35-min sham surgery. In addition to placement on a circulating water bath, mice (n = 6/group) were draped with commercial cling film (CF; Press’n Seal, Glad, Oakland,CA), a conventional paper drape (PD), or no drape (ND) during surgery. Results demonstrated that CF-draped animals had significantly higher rectal temperatures than nondraped animals. Furthermore, surface temperatures of CF-draped mice were considerably higher than those of both paper-draped and undraped animals. The data indicate that cling film is an effective material to help minimize hypothermia in mice and potentially in other laboratory rodents requiring general anesthesia.

POSTHARVEST QUALITY AND CHILLING INJURY OF “SUCCARY” POMEGRANATES AS AFFECTED BY DIFFERENT PACKAGING TYPES

Fully ripe 'Succary' pomegranate fruits were harvested from a private orchard in Ismailia, Egypt in 2015 & 2016 seasons. The fruits were packed in: 1- freely packed fruits (control) 2- sealed fresh bags of high ethylene absorption (HEA) 3- perforated polyethylene )PPE( 4- polyethylene (PE) film (stretchable cling film) 5- commercial PVC (poly vinyl chloride) pages. All packaging treatments were stored at 5 ºC and 90 – 95% RH for 12 weeks. Samples were taken every 2 weeks followed by 4 days at 20˚C. Fruit weight (g) rind thickness (mm), aril /fruit (%), juice content %, juice colour, SSC, acidity%, total sugars%, total phenols% and vitamin C were evaluated at harvest time. Chilling injury of the fruit was reduced by all packaging types. Changes in acidity, and SSC of the packed fruits were lower than that of freely packed fruits (control) during storage period. Cold storage at 5 °C with packaging treatments would be the best for preserving the freshness and vitamin C, increasing antioxidant activity, reducing chilling injury and maintaining fruit quality. Consequently, the fruits were more commercially acceptable.
